CAR-GOUPLING.

SPECIFICATION forming part of Letters Patent No. 268,789, dated December 12, 1882.

Application tiled October 27,1882. (No model.)

To all whom it may concern:

Beitknown that I, JOSEPH GEDDEs, ofltochester, Monroe county, New York, have invented a certain new and useful Improvement in Gar- Gouplings; and I do hereby declare that the following is a full, clear, and exact description of thesame,reference being hadto the accompanying drawings, in which- Figure lis a longitudinal vertical sectionin lineman of Fig. 2. Fig.2is aplan'with the top removed. Fig. 3 is an end elevation of one ofthe draw-heads on an enlarged scale, showing the spring arrangement for turning the shackles.

Y FigA is a plan showing the chain for disengaging the spring. Figs. 5 and 6 are detail Views. My improvement relates to car-couplings in which two shackles are used, provided with barbed heads which engage with catches in the draw-heads.

The` invention consists ,in the construction and arrangement otparts hereinafter described and claimed.

1n the drawings, A Arepresent the two drawheads oftwo meeting carb. These draw-heads differ from ordinary draw-heads in being made very short and having no shank running back under the car, as in the common arrangement.

B B are loops or stirrnps bolted to the bottom ofthe car. The draw-heads rest loosely in these loops, so as to have a limited movenientt'orward and back therein. 0n the back lot' each draw-head is a projecting lug, D, having a slot, a, in its top.

E is a firm stud, projecting downward from the bottom ofthe car and resting in the slot.

slot a, and on opposite sides ofthe stud. When the cars are under motion the strain comes upon the stud E and against one or the other ofthe springs b b, and by this means also the necessary elasticity is obtained to break the shock in either direction. The draw-head is retained in place by tbeloop or stirrup B, before described. By this means the long shank or bar ofthe draw-head ordinarily used is avoided, which simplifies the device and reduces the expense.4

F F are the two'shackles, one attached to' each draw-head. Each consists of a straight rod or bar of iron having a.l flat doublebarbed head, c, at one end,the other end passing to which itis attached, projecting outside, and provided with a coiled spring,f which has a tendency to draw it backward.

g is a square shoulder formed in the bottom of the interior of the draw-head and just back of its mouth.

his a swinging catch, hung in the draw-head above the shoulder g, leavingjust space enough between to allow the barb of the shackle to pass outward in uncoupling when the barb is turned iatwise. The catch, when in a vertical position, is prevented from opening forward by a stop which it strikes; but it is allowed to swing backward in coupling, as will be hereinafter described.

GrV is a flat spring, attached to the side of the draw-head.

H is a lever attached to the shackle, thence extending upward, and connected with the top of the spring by ajointed link, 7c. In the two drawheads the spring attachments are on opposite sides.

I is a chain attached to each draw-head on the saine side where the spring is located, and provided with a pin, l, which passes througha hole, m, in the front of the opposite draw-head, for the purpose of securing the lever, as `will be presently described.

In their natural position the shackles stand with their barbs vert-ical, so thatA when the cars are brought together the barbs will ride up over the shoulder r/ and fall behind, one side engaging with the shoulderg and the 'other b b are two stii' spiral springs, resting in the with the catch h, thus completing the coupling. 'lhe object of the spring attachment is to allow uncoupling. For this purpose the lever H is swung over to the opposite side ofthe draw-head, where it lits into a socket, a, and the pin Z, attached to the chain I ofthe oppoabove the end of the lever, thereby contining the lever. The swinging ot the lever conipressses the spring G, thereby placing the lever under tension; and it also turns the shackle F one-quarter round, so that the barbs lie horizontally' instead of vertically, and in this position they can draw out through the space between the shoulder g and catch h, thereby unthrough a slot, d,.in the back ofthe draw-head;V

site draw-head, is passed through the holem IOO e t I 268,789

coupling the ears. 1n this condition, when the cars are started the first movement draws the coupling-heads out of the draw-bars, and the next movement' straightens the chains I I, draws the pins l Z out of their holes, releases the levers H H, which then spring back to their original position, and turn the shackles up again in position for coupling.

If desired, a chain, p. may be attached tothe chain I, the other end being carried up and attached to the car, as shown in Fig. 6. By this means, when the pin lis drawn from its socket the chain I will be held up and will not fall to the ground.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

l In va `ear-couplimg, the combination of the shackle F, provided with a ilat barbed head, the lever H, attached to the shackle, the spring G, the link k, connecting,` the lever and spring, and the chain I, attached to the opposite drawhead, and provided with a pin, Z, for securing the lever when under tension, as herein shown and described.

In witn ess whereofl have hereunto signed my name in the presence of two subscribing Witnesses.

JOSEPH GEDDES.
